@ Pankti: I hope you know how to google
. If you know that, other things become just easy, though, you still can't expect to spend less time doing such things, but, you can definitely get things done.
Just for some help: Have you ever tried looking at the HTML code of the post? Try taking a look at that and with some trial and error, you can actually learn how to make that post much more customized than blogger lets us do. Have you ever tried composing a document on MS word and pasting in Blogger? You can actually retain the formatting you've done in MS word, and that same formatting, will appear in your blog post.
I too am not aware of too much HTML, CSS, Javascript, and JQuery, but admit that I've done somewhat programming (mainly in Microsoft Visual Basic and associated platforms including VB.NET and VBA), but, I still can implement those things (HTML, CSS, JQuery and Javascript) on my blog, with somewhat trial and error. I've implemented that JQuery and CSS based slideshow as a header in my blog (mind you all the pics used in that slideshow are grown and clicked by me), though it's working on Google Chrome and Firefox, I'm trying to get it work on MSIE as well. In the last two days, I've implemented that menu (that's properly working on Google Chrome only) I'm testing to get it corrected on firefox and MSIE (Internet Explorer). I'm working on some more items including a downloads page that would allow visitors to download the images of flowers that I've grown over a period of time and clicked pictures of with my cellphone.
So, in my opinion, knowing things don't matter much than having an intention to get them done. I'm relatively new to blogging, and thus unaware of blogger platform, which does things quite differently from plain HTML, Javascript and other such things, still, I'm doing it.
